Hello,
  I am having trouble adding an asset to the DMM via the API.  I am using the POST - /xTAS-core/services/content/asset/ method and the DMM is returning 404 Not Found.  Attached is a wireshark packet capture.  It's not really a .txt file, so FYI. The forum interface won't allow me to makeup a file extension.
 
Thanks,
Matt

Hi Walid,   
According to the API Guide (version 0.7.3), there are 2 APIs for adding/uploading an asset.
1)Upload an asset (file)
2)Add an asset from a URL
 
I am using #1.  The only difference in the two API's is the xml:storageType parameter.  There is another parameter that looks suspicious to me.  I wonder if the xml:downloadurl parameter should be 'false' instead of 'true'.  Anyway, the way I understand it, the DMM should pull the file out of the POST body for API #1, not attempt to download it from a URL.  Can anyone from Cisco verify this?
 
Thanks, Matt

I most probably know the reason, but not the solution yet. DMM must be able to resolve the URL you are posting. In your request, you are adding an asset that points to /tmp/file.html. It will give you the error you are getting because DMM wants to resolve it via DNS.   Are you looking for uploading and asset or adding an asset from URL.

Thanks for the response.  Maybe I wasn't clear in my previous messages.  If you look at the attached packet capture, you'll see I am using the multipart form as the API indicates.  The first part is the file part and the second part is the XML part.  I am doing this programmatically (no html page).   I am still getting 404 NOT FOUND.
 
My next plan is to use the HTML page and capture the packets to see if there is a difference.
 
Thanks,
Matt

Hi Hashir,
  I tried using the HTML page to upload the asset and it worked.  It flushed out one problem for me: I was not using the correct category ID.  However, after fixing the category ID, my attempt at uploading the asset programmatically still fails with a 404 NOT FOUND.  I performed packet captures for both the HTML page upload and the programmatic method used my my code.  They are both attached to this thread.  The main difference I see is encoding of the file.  In the HTML page upload, the browser encodes the file in "line-based text."  My code does not do this.  It encodes the file in binary.  My Java code is using HttpClient 4.0.  Do you have sample code that works for this?  If so, I'd like to see it.

Any progress on this?
 
Thanks,

Matt,

Since I last posted on this thread, we have tested HttpClient 3.0. I have pasted (tested) sample code that will work once you edit variables that are specific to your instance of DMM (marked clearly in the code with comments). Please give this a try. I have also attached the Java file to this post for your convenience (you will need to change the extension to .java).

Hashir,
 
   Just a FYI:  the API for 'Upload an Asset' in the Programmer's Guide is incorrect.  This might apply to 'Add Asset from URL' as well.   The URL in the Programmer's Guide is:
/xTAS-core/services/content/asset/
 
The URL in the sample code you sent me:
/xTAS-core/services/content/assets/
 
Note the extra 's' in your URL.  This explains why I was getting a '404 Not Found' when I was testing with HttpClient 4.0.
 
Thanks,
Matt
 
 
 

Hi Hashir,

I have copied and pasted your code into my code, changed the parameters but I got this error message:



The file "Desert.jpg" is at the location specified.

Any ideas why DMM returned an upload failure?

Thanks.
